In the new issue of Rolling Stone, Led Zeppelin's Robert Plant talks about the behind-the-scenes reality of the band's 2007 reunion show in London, and why he won't be playing with his old bandmates again any time soon:

"I've gone so far somewhere else that I almost can't relate to it. It's a bit of a pain in the pisser to be honest. Who cares? I know people care, but think about it from my angle—soon, I'm going to need help crossing the street."

He also trash-talks fellow aging rockers who are still playing their old hits:

"There's  nothing worse than a bunch of jaded old farts, and that's a fact," he says. "People who have written their story — they've gotten to the point where nothing moves. I don't deal in that, and I don't deal with anybody who deals in that."

Plant says he'd rather turn his attention to projects like his well-received Band of Joy project, and a follow-up to his acclaimed 2007 collaboration with Alison Krauss. Though he said he abandoned their latest project because "the sound wasn't there," Plant has still got a whole lotta love for the bluegrass singer. "Alison is the best. She's one of my favorite people. We'll come back to [the project]."
